Structural metadata with undefined sections causes odd behavior for lil' scrub #3047
For items with structural metadata, when the defined spans don't cover the entirety of the item duration--but leaves areas of the item undefined--lil' scrub displays odd behavior.
Behavior 1: when playback is in an undefined section, lil' scrub moves in proportion to the entire item.
Behavior 2: when playback is in a defined section, lil' scrub moves in proportion to the defined section.
Disparity: playing from, clicking from, or dragging the timestamp from an undefined section into a defined section causes an abrupt switch from Behavior 1 to Behavior 2.
